"The Lac des Bois map area (NTS 96-K) lies within the Colville Hills region of the Northwest Territories. Sparse bedrock exposures in the area include carbonate and siliciclastic strata ranging from Cambrian to Paleogene. These strata were deformed in the Cretaceous to Eocene by folding and contractional faulting associated with Cordilleran deformation. A pre-Cordilleran set of approximately north-trending extensional faults are preserved within subsurface Proterozoic and Cambrian strata, and were locally reactivated by Cordilleran deformation. A major unconformity between Devonian and Cretaceous strata is marked by tilted Paleozoic strata beneath the Cretaceous, and the absence of Devonian strata in the eastern part of the map area. Natural gas has been reported from petroleum exploration wells drilled into Mount Clark Formation (Cambrian) sandstone"--Abstract.
